Shocking video shows high school teacher, 68, lying unconscious in hallway after being knocked out by a STUDENT

This is the shocking moment a Philadelphia high school teacher was filmed lying unconscious in a hallway after allegedly being knocked out by a student.

Pewu Johnson, 68, a substitute English teacher, reportedly reprimanded the teenager after he saw a girl sitting on his lap in an 'inappropriate' manner at Bartram High School.

Later that day, the student confronted Mr Johnson and told him, 'get the f*** out of my face', before throwing him to the ground, causing him to smack his head against the floor, school officials said.
